SPECIFICATION forming part of Letters Patent No. 532,545, dated J' anuary 15, 18957.

Application filed september 4,1894. sain No. 522,061. (No man.)

To all whom it may concern.' f Be it known that I, JOHN F. DORNFELD, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Malting-Floors, ofjwhich the following is a description, reference being had to the accompanying drawings, which are a part of this specification. p My invention has relation to improvements in malting iioors.

In perforated malting lioors it is necessary that the under side thereof should be thoroughly cleaned at frequent intervals. Heretofore, this has only been accomplished with considerable difficulty.

It is one of the objects, therefore, of my invention to provide a sectional malting door so constructed and arranged that the above-de scribed end can be attained with but the expenditure of the slightesttrouble andtime, the sections being all of one shape and size, and capable, when necessary, of being removed separately, without disturbing or disarranging in the least any of the other sections.

With the above and'other objects in view the invention consists of the devices' and parts, or their equivalents, as hereinafter more fully described and claimed.

In the accompanying drawings, Figure 1, is a perspective view of Ymy invention, illustrating four longitudinal lines of sections, some of said sections being shown Vas thrown up vertically, for theV purpose of permitting the under sides thereof to be cleaned. Fig. 2, is a fragmentary end elevation, a part being broken away, and showing severaldotted line positions of the sections. Fig. 3, is a plan view at a point where one of the legs supports the corners of four adjacent sections, said sections being shown in dotted lines. Fig. 4, is a view of theleg illustrated in Fig. 2, at right angles to the position shown in said figure. FigJ, is a view, partly in section, of one of the intermediate legs. Fig. 6, is a plan view of the leg illustratedin Fig. 5, the sections of floor being shown ,in dotted lines, audFig. 7, is a front elevation showing an arrangement for three longitudinal linesof sections.

Like numerals of reference denote like parts f throughout the several views.

Referring to the drawings, the numeralsS,

8, indicate side boxes or air ues which rest upon the floor proper of a malting room, and between which boxes the malting floor heref inafter described is arranged. Tracks 9 are secured to the tops of the boxes, upon which tracks a carriage is adapted to travel. These side boxesor flues are provided with top openings, such as 10, regulated by means of lids or covers 11. To these boxesattemperated air is fed', said air passing through the openings 10, and thence drawn down to and through the openings of the malting floor to the space between the under side of said malting floor and the iioor proper of the room. From these spaces suitable exhaust passages (not shown) conduct the air.

The malting floor is composed of a series of perforated sections 12, of the same size and shape, said sections arranged in a series of longitudinal lines, as clearly shown in Fig. 1.

Referring now particularly to the arrangement shown in Fig. l, the numeral 13 indicates a series of legs arranged in two longitudinal lines,and the n umeral14 a series of supporting legs arranged in a longitudinal line intermediate the two lines of legs 13. The latter legs are provided with lower flanges 15, which are securely bolted to the floor proper. Secured at the upper ends of -these legs, upon opposite sides are castings 16, 16, which have their top edges semi-circularly recessed, as indicated at 17, the ends of said semi-circular recesses being shouldered, as indicated at 18, 18. The inner one of each of these castings is formed or provided with a transverse bar 19, which bar in turn is provided at'opposite endswith laterally-projecting fingers 20, 20.

The sections of ioor are provided with depending rims 21, the adjacent edges of which rest in the semi-circular recesses 17 of the castings 16. Hooks 22 depend from one end of each section of floor, said hooks adapted to engage the laterally projecting fingers 20, as hereinafter explained. As will be seen from Fig. 1, the inner edges of the outer lines of sections, and the outer edges of the'inner lines of sections are supported uponthe legs 13, whilev the outer edges of the outer sections are supported on ledges 23 secured to the side boxes, and the' inner edges of the inner sections upon they legs 14. These legs 14 it loosely and removably in sockets 24 secured IOO to the floor of the malting room. Their upper ends are enlarged, and upon the fiat circular top of each enlargement is formed a series of annular edge lugs 25, and a central pyramidal lug 26. Each one of the sections has the lower edge of a part of its rim cut away, as indicated at 27, said cut away portions conforming to and adapted to lit against one of the triangular sides of the pyramidal lugs, whereby the legs 14 are maintained in perpendicular position. As the legs 14.- iit loosely and removably in their sockets, it is obvious that when all the four sections are removed from engagement with one of these legs said leg is no longer supported, and hence does not stand upright. If, however, only one section of malting iioor is in engagement with a leg 14, said leg will be maintained upright by reason of the provision of the lugs 25. Inasmuch as the central line of legs 14C are thus made readily removable, it is obvious that the two inner longitudinal lines of sections may be readily removed at any time, and the space utilized for other purposes, if desired.

In Fig. 1 of the drawings a number of the sections 12 are shown as supported in their raised or vertical positions for the purpose of gaining access to and cleaning the botto ms thereof. In Fig. 2, the manner of accomplishing this is clearly illustrated. In the inclined dotted line position on the right of Fig. 2 the section is shown as raised sufficiently to permit its edge to engage the shoulder 18. As the section is raised the hook 22 is, of course, raised therewith, and when the section assumes the vertical dotted line position, said hook will engage the laterally-projecting iinger 20, whereby the section is maintained in its raised vertical position. All the other sections are raised in exactly the same manner, each section resting upon its respective shoulder 18, and supported by its respective hook 22 engaging one of the fingers 20.

In Fig. 7 is shown an arrangement by means of which only three longitudinal lines or sections may be employed. In this form, the legs 13 are disposed only in one longitudinal line, while another line ot' legs 28 are placed parallel thereto, said line of legs having castings 29 secured thereto, the castings having horizontally-projecting lugs 30 extending from one side, and upward-curved fingers 31, provided with shoulders 32, projecting from the other side. Only one line of sections are raised upon theselegs 2S. The outer edges of the sections when in their horizontal positions rest upon the ledge23 of the side box adjacent. The edges of the sections of the supporting legs 13, rest, respectively, upon the ledge 23 of the other side box and the horizontal projecting lugs 30 of the castings 29.

When it is desired to use only two longitudinal lines of sections, it is obvious that only the supporting legs 13 are employed, and the outer edges of the sections under such circumstances rest directly on the ledges 23.

From the above description it will be seen that I provide a construction of malting floor wherein the cleaning of the underside there of may be readily accomplished. The sectional tloor can also be made of any Width, and when desired the sections can be separately removed and replaced by others, when damaged, or otherwise impaired, without the necessity of disarranging any of the remain ing sections.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, with supporting legs provided with shoulders and with projecting lingers, of door sections normally resting hori- Zontally on the legs, said sections provided with depending hooks, which, when the sections are raised to vertical positions and rest upon the shoulders, engage the proj ccting fingers, and maintain said sections in their vertical positions, substantially as set forth.

2. The combination, of supportinglegs having recesses at their upper ends provided with end shoulders, a transverse bar provided with laterally-extending fingers, door sections provided With depending rims, the rims of adjoining sections resting in the recesses of the legs, and hooks pivoted to the sections, and adapted, when the sections are raised to vertical positions and rest upon the shoulders, to engage the projecting fingers, and maintain said sections in their vertical positions, substantially as set forth.

3. The combination, with supporting legs fitting loosely and removably in sockets, each leg having its upper end provided with edge lugs, of iioor sections provided With depending rims adapted to fit over the edge lugs of the legs, substantially as set forth.

4:. The combination, with supporting legs iitting loosely and removably in sockets, each leg having its upper end provided with edge lugs and with a central pyramidal lug, of door sections provided with depending rims, said rims fitting over the edge lugs, and having cut-away portions fitting against the sides of the central pyramidal lug, substantially as set forth.

5. The combination, of supporting legs arranged at a distance apart in longitudinal lines, a series of iioor sections also arranged in longitudinal lines and supported on said legs, and mechanism carried by the iioor sections and by the supporting legs, respectively, and adapted, when the door sections are turned up to Vertical positions for cleaning purposes, to engage or interlock, whereby the sections are retained in their vertical positions, substantially as set forth.
